Glossary

ROMB

— RAID on motherboard.

rpm

— Revolutions per minute.

RTC

— Real-time clock.

SAS

— SCSI Attached Storage.

SATA

— Serial Advanced Technology Attachment. A

standard interface between the system board and storage
devices.

SCSI

— Small computer system interface. An I/O bus

interface with faster data transmission rates than standard
ports.

SDRAM

— Synchronous dynamic random-access

memory.

sec

— Second(s).

serial port

— An I/O port used most often to connect a

modem to your system. You can usually identify a serial
port on your system by its 9-pin connector.

service tag

— A bar code label on the system used to

identify it when you call Dell for technical support.

simple disk volume

— The volume of free space on a

single dynamic, physical disk.

SMART

— Self-Monitoring Analysis and Reporting

Technology. Allows hard drives to report errors and failures
to the system BIOS and then display an error message on
the screen.

SMP

— Symmetric multiprocessing. Used to describe a

system that has two or more processors connected via a
high-bandwidth link and managed by an operating
system, where each processor has equal access to I/O
devices.

SNMP

— Simple Network Management Protocol. A

standard interface that allows a network manager to
remotely monitor and manage workstations.

spanning

— Spanning, or concatenating, disk volumes

combines unallocated space from multiple disks into one
logical volume, allowing more efficient use of all the space
and all drive letters on a multiple-disk system.

striping

— Disk striping writes data across three or more

disks in an array, but only uses a portion of the space on
each disk. The amount of space used by a "stripe" is the
same on each disk used. A virtual disk may use several
stripes on the same set of disks in an array. See also

mirroring

, and

RAID.

SVGA

— Super video graphics array. VGA and SVGA are

video standards for video adapters with greater resolution
and color display capabilities than previous standards.

system board

— As the main circuit board, the system

board usually contains most of your system’s integral
components, such as the processor, RAM, controllers for
peripherals, and various ROM chips.

system configuration information

— Data stored in

memory that tells a system what hardware is installed and
how the system should be configured for operation.

system diskette

— See

bootable diskette

system memory

— See

RAM

System Setup program

— A BIOS-based program that

allows you to configure your system’s hardware and
customize the system’s operation by setting features such
as password protection. Because the System Setup
program is stored in NVRAM, any settings remain in
effect until you change them again.

system.ini file

— A start-up file for the Windows

operating system. When you start Windows, it consults
the

system.ini

file to determine a variety of options for the

Windows operating environment. Among other things,
the

system.ini

file records which video, mouse, and

keyboard drivers are installed for Windows.

TCP/IP

— Transmission Control Protocol/Internet

Protocol.

termination

— Some devices (such as the last device at

each end of a SCSI cable) must be terminated to prevent
reflections and spurious signals in the cable. When such
devices are connected in a series, you may need to enable
or disable the termination on these devices by changing
jumper or switch settings on the devices or by changing
settings in the configuration software for the devices.
